Assign List<SimpleStringProperty> to multiple TableColumns - javafx

Question

I'd like to have a tableView like below:
id | b | a | choiceBox
--------------------------
0 | 0 | 0 | 0/1
1 | 0 | 1 | 0/1
2 | 1 | 0 | 0/1
3 | 1 | 1 | 0/1
I get the IDs depending on a Choice Box value into my table. But i dont know how to assign a my List bits to multiple columns (i.e a,b,c....
I tried using the example given here:How can I associate data (List<SimpleStringProperty> with the table columns of a table view
But didn't work.
Also how do i add the Choice Boxes to a last column.
MWE:
